In mathematics, an image is a value or set of values of a function.
Specifically, let f be a function from the setX to the set Y.
If a is an element of X, then its image under f is the value f(a).
If A is a subset of X, then its image under f is defined to be f(A) := {f(a) : a in A}.
Finally, the image of f itself is f(X), the same as the range of f.
In religion, an image is an idol or icon.
In philosophy, an image is a conception or idea.
In Comics, Image is a publisher of such characters as Spawn. See Image Comics.
